Release History

Renew 2.5

Renew 2.5 was released in June 2016.

Modifications

• Most obvious is the complete reimplementation of the Navigator plugin. It is now persistent, extensible and the tree view can now be filtered. We optionally provide some convenient extensions, such as the integration of the drawing’s diff feature (ImageNetDiff), which can now be triggered directly from the Navigator GUI.
• The FreeHEP library has been upgraded to version 2.4.
• The quick-draw feature has been improved, which results in a reduction to half the amount of mouse clicks during quickly drawing net elements.
• Some key-bindings are now configurable.
• The log4j configuration and the configuration GUI have been improved.
• The individual log4j configuration file now resides in folder renew, which is located in the users home folder. The default location for log files moved there, as well.
• The loading of plugins at startup can now be black-listed or white-listed.
• The PDF export produces PDF documents with bounding boxes; configuration has been fixed.
• The grid can now be adapted and it can be activated as default.
• Several console commands have been improved, including the following plugin commands: list, load, unload and also export command ex. Type help to print a synopsis of all commands.

Additions

• The Console plugin replaces the Prompt plugin. It employs the well-established JLine2 libray and provides several improvements: tab-completion for commands and attributes, command history and editable command line.
• The Quick Fix feature improves the reporting of syntax errors by providing suitable proposals for remedies and their automatic realization.
• The Refactoring plugin (optional) provides features such as renaming of variable or renaming of synchronous channels.
• Drag & drop now works for Renew drawings. Simply pull the drawing over Renew’s main window. Drawings and also folders can also be dragged into the Navigator Window. Additionally you can add images to a drawing by dragging it on the drawing’s window.
• Two new text tools have been added. One is the target text tool, which allows to add hyperlinks to any drawing element. The targets can be other model artifacts, for instance a net, or external resources referenced by a URL. The hyperlink is activated by using the Ctrl modifier key together with a mouse click. The comment tool allows to quickly add comments to a drawing element.

Removals

• Macao format has been removed, since its usability was very limited.
• The PostScript export has been removed. Use EPS export or PDF export instead.

Renew 2.4.3

Renew 2.4.3 was released in September 2015

This is a maintenance release that provides an update of the FreeHep library and a new version of the Mac OS X application bundle. It fixes issues concerning the export functionality with newer Java versions. This version requires at least Java 7.

Renew 2.4.2

Renew 2.4.2 was released in January 2015.

This is a maintenance release that provides a fix for the import of reference nets from PNML format (RefNet).

Renew 2.4.1

Renew 2.4.1 was released in May 2014.

This is a maintenance release that provides a fix for a race condition that occurs - under rare conditions - during the termination of the simulation.

Renew 2.4

Renew 2.4 was released in May 2013.

Modifications

• The support for the .xrn format is discontinued. We encourage the use of PNML instead.
• We fixed Remote Server connection (RMI) by providing configuration (see the User Guide Section 2.6.9).
• We have fixed the simulation database backing and adapted the mechanism for MySQL / InnoDB.
• Remaining AWT dialogues have been converted to Swing.
• The Logging GUI has been improved by decoupling the Simulator from the GUI.
• The loadrenew script now starts a regular Renew instance if the connection to a Drawing Load Server is not possible.
• The desktop integration for Linux and Windows have been improved.
• We provide new unified icons for all operating systems.
• Many minor bugs have been fixed. Some of these were:
• Rare problems with locating nets relative to the classpath have been solved.
• Changes on the line style now affects all figures.
• The font style underlined now also affects small font sizes.
• Export to PNML now always produces files in UTF-8 character encoding.
• The Logging tab of the Configure Simulation dialog has been revised.
• The log4j PatternLayout can now be set from within the GUI
• Custom file appenders created in Logging GUI are now functional.
• Net components are more robust if attached figures are manipulated.
• It is now possible to escape whitespaces in command line commands. In that way it is possible to open drawings with whitespaces in the path from command line.

Additions

• The Navigator now offers a button to recursively expand a directory sub-tree.
• The Navigator now loads directories without locking the GUI.
• PNML and ARM files are shown in the Navigator.
• The keyboard shortcut Ctrl+Enter closes the text editor overlay.
• The background transparency of EPS files can now be controlled by setting the property de.renew.io.export.eps-transparency.
• Windows: The installation script installrenew.bat creates reg files that associate and disassociate Renew drawing files with loadrenew.bat and register icons.
• We provide deb packages for Debian-based systems.

Relevant for Developers

• We refactored large parts of the code base.
• Many Java compiler warnings have been resolved and Javadoc documentation have been improved.
• A few more JUnit tests have been introduced.
• Logging and the simulator have been partially reworked to allow deadlock-free real-time (GUI) logging with only minimal time delay.
• Several tools that were originally mandatory to build Renew are now optional: these are Cobertura, Jalopy, JUnit and Latex.

(previously only files from last jar file were loaded)

Renew 2.2

Renew 2.2 was released on 2009/08/28.

This release introduced the FreeHep vector graphics package for screen presentation and to support additional export formats like PDF, PNG and SVG. Several improvements were made to attributes of drawing figures and to user interaction via mouse and keyboard (see user guide for details).

Internally, all simulation-related code is now executed within specific threads. This allows to configure a separate priority for simulation threads and improves the loading of user-defined classes in the simulation context.

Java 1.5 is now required for compiling and running Renew.

Renew 2.1.1

Renew 2.1.1 was released on 2008/07/25.

This was a maintenance release that provided several minor bug fixes for PNML export, null token display and access to public methods of private (inner) classes in Java expressions.

The experimental AppleUI plugin now supports building an MacOS X application bundle.

Renew 2.1

Renew 2.1 was released on 2006/05/26.

This release introduces the Apache Log4J logging framework for all Renew components (except the console prompt).

Fixed several minor bugs.

The color and font attribute dialogs were improved.

Whitespace-only inscriptions are now deleted automatically (like empty ones).

Renew 2.0.1

Renew 2.0.1 was released on 2004/10/08.

This was a maintenance release that provided bug fixes for the install scripts and some redraw issues of the graphical net editor.

An experimental AppleUI plug-in is available as optional download. It provides rudimentary integration with the MacOS look and feel.

Renew 2.0

Renew 2.0 was released on 2004/06/18.

This release introduces a plug-in architecture to Renew. The application was decomposed into several plug-ins.

Java 1.4 is now required for compiling and running Renew.

The simulation engine was restructured. The handling of the various configuration properties has been canonised by the plug-in system. The ability to switch simulator modes, net formalisms, the net loader path, and the remote access feature on the fly was added. The class loader for custom classes has changed.

The GUI application classes were restructured and (partly) converted to use the Swing package from the Java foundation classes. A PNML-compatible export format was added. The editor is able to load drawings from URLs. The net loader can now search nets relative to the classpath.

The :net() channel is no longer invoked implicitly on instance creation. The RenewMode interface provided by the GUI has been removed. In consequence, the start scripts for the modes disappeared, too. The channel, name and isolated node checks have been removed from the Net menu because they need to be adopted to the new simulator architecture. The expanded token display feature has moved into the optional fs plug-in, this option has no effect unless the fs plug-in is installed.

Renew 1.6

Renew 1.6 was released on 2002/10/25.

This was a feature release, but it also included various small bug fixes throughout the code.

Renew requires Java 1.2 or higher now.
